With a total of 5 patents to her name, her work has had a profound impact on the efficiency and quality of printing technologies.

Latest Patents

One of her latest patents is a "Computerized memory mapping method for transforming color data." This method is designed for implementation in computer systems to correct and half-tone color data in a list of colors. The process begins with the first color in the list, where color corrections are performed. Traditional half-toning methods are utilized to determine the printable dots for each position in the halftone matrix for that color. This process is repeated for each color in the list, resulting in a compiled lookup table. As each pixel of the image is processed, the printable dots are determined by referencing this lookup table.

Another notable patent is the "Drop count-based ink-jet pen servicing method." This invention describes an automatic print rate-controlling and pen-servicing method for ink-jet printers. The preferred method involves counting the number of drops of ink fired from each pen in the printer's printhead carriage. This information is used to manage power and determine appropriate servicing intervals for the pens. The counts are maintained in memory connected to the printer's microcontroller, which uses them to control print rates and servicing frequency based on predefined criteria.
